IMPROVEMENT IN SAFETY ATTACHMENTS FOR GAS-PIPES.

Specification forming part of Letters Patent No. 56,836, dated July 31,1866; antedated May '7, 1866.

To all whom it may concern Be it known that we, L. W. TURRELL, SAM- UELSTANTON, and L. C. WARD, of N ewburg, in the coun ty ofOran ge and Stateof New York, have invented a new and Improved Safety Attachment for theGas-Pipes of Oil-Wells; and we do hereby declare that the following is afull, clear, and exact description thereof, which will enablethoseskilled in the art to make and use the same, reference being hadtothe accompanying drawings, forming part of this specification, inwhich- Figure l is a longitudinal section of our invention, taken in theline :v Fig. 2 5 Fig. 2, a transverse section of the same, taken in theline y y, Fig. l.

Similar letters of reference indicate like parts.

In pumping up oil from oil-wel1s the fuel used for generating the steamwhich drives the pump consists wholly or partially of the gas whichissues from the wells. This gas is conveyed, by means of a tube, fromthe Well to the furnace of the steam-boiler. It is an inexpensive fuel,but is attended with danger on account of being so very iniiammable, thegas being liable to ignite at the junction of the gas-pipe with thefurnace and cause an eXplosion destructive to life and property.

Our invention consists in inserting in the gas-pipe, at a point betweenthe well and the furnace of the steam-boiler, one or more partitions ofwire-gauze or wire-cloth, so as to prevent, in case of the ignition ofthe gas, the flame communicating with the gas in the well, it being wellknown that a flame cannot pass through wire-gauze or fine wire-cloth.

- A represents acoupling, which connects the two parts, B B, of agas-pipe for an oilfwell,

and C represents a series of Wire-gauze or wirecloth partitions, betweenwhich skeleton disks or rings D are interposed in order to admit ofsuitable spaces being between the partitions, as shown in Fig. l. Thesewire-gauze parti' tions C and disks or rings D are secured between theends of the two parts B B of the gas-pipe by the coupling A, as shownclearly in Fig. l.

We do not confine ourselves to any particular means or arrangement forsecuring the wire-gauze partitions within the gas-pipe 5 nor do `weconflne ourselves to any particular number of said partitions, as onemay be used, but a plurality of them would be most advisable.

By this invention the llame, in case the gas within the gas-pipe ignitesnear the furnace, cannot be conveyed or communicated to the well, as thewire-gauze partitions will prevent the passage of the flame throughthem. Hence the danger of explosions from that cause will be fullyobviated. The gas, it will be understood, will pass freely through thepartitions.

We claim as new and desire to secure by Letters Patent- The combinationof the gauze disks O O O, rings D D, and coupling A B, arranged andapplied in the manner and for the purposes specified.
